Hello Mark!

I have found the necessary information to control the GPIO.
But what about the I2C and SPI interface?

I don't find usefull information about this. I want native
support for my projects. Don't want to make a software based
(bit-bang) I2C or SPI interface with the GPIO pins.

Best regards,
Johannes
